The pair stopped off at the property yesterday to record a video tour for fans - but they couldn't believe how much show boss Simon Cowell must have splashed out on the property after seeing it in the flesh.

"Oh my days," gushed Marvin. "This is the size of five houses in one!"

The duo were then greeted at the door by Cheryl Fernandez-Versini's girl group Alien Uncovered, who led them into the kitchen where the other contestants were all gathered.

As a tribute to her mentor, Kiera pointed out that she had written "I love Rita" on the frame of her bed.

Meanwhile, room two is now the new home of Reggie & Bollie, Max Stone and Anton Stephans, room three hosts Alien Uncovered while room four is occupied by Che Chesterman, Sean Miley Moore and Mason Noise.

While the contestants' bunk beds did not appear too glamorous, they revealed that underneath their covers, each of them had been given a custom made mattress.

Bupsi revealed: "My mattress reads, 'Team Simon. The performance of the night.' The only thing I don't like about it is it should say 'If you want nasty, I'll give you nasty'. That's the only thing I would change, Simon!"

Each bedroom features en-suite bathrooms with televisions facing the tubs, as well as walk-in wardrobes. The contestants also have access to a huge swimming pool.

"I can't even swim but I would learn if it meant i could spend some time in there," Melvin joked.
